i have to agree with whiteknight on one point. SW just always seemed childish and immature to me, even when i was a kid. i know its science fiction but all the good vs evil talk and the whole space cowboy style of the series seems like something you would find in every sf novel in the fifties. to me it's just not a believable material. and you have to admit, some of those aliens in the tatooine bar and jabba's lair really s*cked serious a$$ so you cant talk of any suspension of disbelief there. and i wont even say a word about those frakkin furry ewoks. always givin me the creeps. i tried to like SW universe, i really did, but when it comes down to it, it's a joke.
on the other hand, imho ST (post-TOS), altough a bit dry at times, always had a much realistic sense for what is possible and what is not. the crew on enterprise, ds9 and voyager, eventho somewhat idealised, were sf characters you could find common ground with. but always there was this idea of bettering ourselves, not only through technology, but our ideals and actions, as individuals well as one human species. for me, ST always represented what we strived to become, and SW what we have been in the past, only wrapped up in shiny futuristic packaging. and unlike many others, i actually enjoyed every ST series, especially the voyager (first ST series I ever saw) and st enterprise (anyone who never saw season 3 episode 10 "Similitude", should do so right away. i mean it).
ST is just better. way better.
